Important part was in the next paragraph. Floyd scared to lose the "0".

"I think Floyd Mayweather thinks he's going to beat Manny Pacquiao. He will be the favorite. What Mayweather is afraid of more than anything else is an L, a loss. He has marketed himself as this unbeaten and unbeatable fighter, and to a lot of new fans or unsophisticated fans, they think that's a big, big deal, which it never has been, because if you fight enough good, young fighters in their prime, somebody's gonna beat you."
